An assembly of devices designed to evacuate fluid, tissue, gas, or other foreign materials from a body cavity or lumen by means of suction. It generally consists of a suction pump powered by compressed air or oxygen from a hospital's central gas system, tubing, plastic/glass collection container(s), a vacuum gauge, a regulator, an overflow trap, a moisture filter, and possibly a microbial filter. The pressurized gas enables the pump to create a vacuum in the suction tubing, which is inserted into the body for the removal of materials into the collection container. This system can be used in a wide variety of hospital or other healthcare settings.
